Description

Chip system and control method

Technical Field

The present application relates to the field of communications technologies, and in particular, to a chip system and a control method.

Background

The smart watch is used as a wearable mobile device and has various data processing functions such as conversation, navigation, monitoring, payment and interaction besides the function of indicating time. Because the design space of the intelligent watch is limited, the battery capacity of the intelligent watch is inevitably limited, and therefore, how to improve the endurance time of the intelligent watch to the maximum degree under the limited battery capacity becomes a difficult problem to be solved.

The prior art provides a control device comprising a main control subsystem and a secondary control subsystem, which control the smart watch in different states by switching the different subsystems to reduce the power consumption in the smart watch. Fig. 1 is a schematic structural diagram of a control device of a smart watch, which has an operating state and a sleep state (i.e., an off-screen state). As shown in fig. 1, the control device includes: the system comprises a main control subsystem, a secondary control subsystem, a display subsystem and a switching module. The display subsystem is connected with the switching module, the switching module is respectively connected with the main control subsystem and the auxiliary control subsystem, and the main control subsystem is connected with the auxiliary control subsystem. Specifically, when the main control subsystem detects that the intelligent watch enters a dormant state, first state synchronization information is sent to the auxiliary control subsystem, after the auxiliary control subsystem receives the first state synchronization information, the auxiliary control subsystem obtains the control right of the display subsystem through the switching module so as to control the display subsystem, and the first state synchronization information is used for indicating that the intelligent watch is in the dormant state; when the intelligent watch is in a dormant state, the auxiliary control subsystem receives a wake-up signal and then sends second state synchronous information to the main control subsystem, the second state synchronous information is used for waking up the main control subsystem, and after the main control subsystem is waken up, the control right of the display subsystem is obtained through the switching module so as to control the display subsystem.

When the intelligent watch is in the dormant state, the main control subsystem is in the dormant state, and the power consumption of the main control subsystem is higher than that of the auxiliary control subsystem generally, so when the intelligent watch is in the dormant state, the auxiliary control subsystem controls the display subsystem, the power consumption of the intelligent watch can be reduced, and the endurance time of the intelligent watch is prolonged. However, the auxiliary control subsystem only controls the display subsystem when the intelligent watch is in a dormant state, and when the intelligent watch is in a low-power-consumption working state, the display subsystem is still controlled by the high-power-consumption main control subsystem, so that the power consumption is not obviously reduced.

The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c may represent: a. b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or plural. In addition, the embodiments of the present application use words such as "first," "second," etc. to distinguish between the same item or similar items that have substantially the same function and effect. For example, the first threshold and the second threshold are merely for distinguishing between different thresholds, and are not limited in order. Those skilled in the art will appreciate that the words "first," "second," and the like do not limit the number and order of execution.

Fig. 2 shows a schematic structural diagram of a smart watch with a long endurance, the smart watch comprising: the system comprises a master control unit, a slave control unit, an enabling control unit and a power management unit. The enabling control unit is respectively connected with the main control unit, the auxiliary control unit and the power management unit, and the auxiliary control unit is respectively connected with the power management unit and the main control unit. When the intelligent watch is in a high-load state, the master control unit and the slave control unit are both in a working state and are respectively used for controlling the intelligent watch; when the intelligent watch is in a low-load state, the master control unit is in a non-working state, and the slave control unit is in a working state and controls the intelligent watch, so that power consumption of the intelligent watch is saved. Specifically, when the smart watch is in a high-load state, the main control unit outputs a first voltage signal to the enabling control unit, the enabling control unit receives the first voltage signal and outputs an enabling signal EN, the power management unit receives the enabling signal EN and provides power supply voltage for the slave control unit, and the main control unit and the slave control unit are both in working states. When the intelligent watch is in a low-load state, the main control unit is in a non-working state, the slave control unit outputs a second voltage signal to the enabling control unit, the enabling control unit receives the second voltage signal and outputs an enabling signal EN, and the power management unit receives the enabling signal EN and provides power supply voltage for the slave control unit, so that the slave control unit is in a working state, and therefore energy consumption is reduced when the intelligent watch is in the low-load state. In the structure, the master control unit and the slave control unit are respectively realized by adopting different chips, so that the complexity of the process is improved and the cost of the intelligent watch is increased when the master control unit and the slave control unit are applied to the intelligent watch.

Based on the above, the embodiment of the application provides a chip system and a control method, wherein the chip system is applied to electronic equipment, and the electronic equipment can be an intelligent watch. The chip system can directly control the intelligent watch through the low-power-consumption processing unit when the intelligent watch is in the low-power-consumption state, and the intelligent watch is controlled through the low-power-consumption processing unit without waiting after the intelligent watch is in the dormant state (namely, the screen-off state), so that the power consumption of the intelligent watch is reduced, and the endurance time of the intelligent watch is prolonged.

Fig. 4 is a schematic structural diagram of a chip system according to an embodiment of the present application, where the chip system is applied to the electronic device shown in fig. 3, and the chip system includes: a first general processing unit 201, a first graphic processing unit 202, a second general processing unit 203, a second graphic processing unit 204, and a storage unit 205; wherein the first general processing unit 201, the first graphic processing unit 202, and the storage unit 205 are coupled by a physical interface, and the second general processing unit 203, the second graphic processing unit 204, and the storage unit 205 are coupled by a physical interface; when the power consumption of the electronic device is greater than a preset threshold, the first general processing unit 201 and the first graphics processing unit 202 enter a power-on state; when the power consumption of the electronic device is less than or equal to the preset threshold, the second general processing unit 203 and the second graphics processing unit 204 enter a power-on state, the first general processing unit 201 and the first graphics processing unit 202 enter a power-off state, the storage unit 205 includes a memory, and one general processing unit of the first general processing unit 201 and the second general processing unit 203 accesses the memory at the same time.

The preset threshold value can be set according to actual requirements and experience of related technicians. The embodiment of the present application is not particularly limited thereto.

In addition, the power of the first general purpose processing unit 201 is greater than the power of the second general purpose processing unit 203, and the first general purpose processing unit 201 may also be referred to as a high power consumption processing unit, for example, the first general purpose processing unit 201 may be a high performance processor core. The second general purpose processing unit 203 may also be referred to as a low power consumption processing unit, for example, the second general purpose processing unit 203 may be a low power consumption processor core. In one example, the first general purpose processing unit 201 is a central processing unit (central processing unit, CPU) and the second general purpose processing unit 203 is a micro control unit (micro controller unit, MCU). The first general processing unit 201 and the second general processing unit 203 are two processing units that are independent of each other, i.e. the first general processing unit 201 and the second general processing unit 203 can be independently powered on.

Furthermore, the first GPU 202 is more accurate and complex than the second GPU 204, such that the first GPU 202 is operated at a higher power than the second GPU 204. By way of example, the first graphics processing unit 202 may be a three-dimensional (three dimensional, 3D) graphics processing unit, for example, the first graphics processing unit 202 may be a 3D graphics rendering core for processing complex and high precision 3D graphics. The second graphics processing unit 204 may be a two-dimensional (2D) graphics processing unit, for example, the second graphics processing unit 204 may also be a 2D graphics rendering core for processing simple 2D graphics. In one example, the first graphics processing unit 202 is a three-dimensional graphics processor (three dimensional graphics processing unit,3D GPU) and the second graphics processing unit 204 is a two-dimensional graphics processor (two dimensional graphics processing unit,2D GPU).

Second, the first general processing unit 201 and the first graphics processing unit 202 may be referred to as a high power consumption processing system. The high power processing system may also be referred to as a high performance processing system or a multifunctional operating system (RICH operating system, RICH OS), which may support the electronic device to enter complex (RICH) application scenarios, for example, the high power processing system may support the electronic device to enter application scenarios such as 3D dial, video playing, mobile phone (including cellular phone), and music playing.

The second general processing unit 203 and the second graphics processing unit 204 may also be referred to as a low power processing system. The low power processing system may also be referred to as a real-time operating system (RTOS), and may support the electronic device to enter into a simple application scenario, such as any one of a 2D dial, bluetooth talk, time display, sports health, and information display.

The storage unit 205 may be configured to store information in the electronic device, for example, the information may include payment information, time information, and the like, and the storage unit 205 may include a memory (for example, the memory may be a random access memory), where one of the first general processing unit 201 and the second general processing unit 203 accesses the memory at the same time. For example, when the first general purpose processing unit 203 and the second general purpose processing unit 203 are separately in a power-on state, the general purpose processing unit in the power-on state accesses the memory. The first general purpose processing unit 203 accesses the memory while the first general purpose processing unit 203 and the second general purpose processing unit 203 are simultaneously in a powered-on state. Optionally, the storage unit 205 may further include a storage device granule and a storage control system for controlling the storage device granule.

It should be noted that, the first general processing unit 201 and the second general processing unit 203 entering the power-on state includes the first general processing unit 201 and the second general processing unit 203 entering the power-on state and entering the working state. The first graphics processing unit 202 and the second graphics processing unit 204 entering the power-on state only includes the first graphics processing unit 202 and the second graphics processing unit 204 entering the power-on state and not entering the working state. When the electronic device needs to process graphics, the first general processing unit 201 controls the first graphics processing unit 202 to enter the working state, or the second general processing unit 203 controls the second graphics processing unit 204 to enter the working state.

The functions of the respective units in the chip system will be described below.

The first general processing unit 201 may be configured to detect power consumption or an application scenario of the electronic device, where the application scenario may include, for example, a 2D dial, a time display, a sports health, an information display, a mobile payment, a mobile phone call, a video playing, a music playing, or a 3D dial (may also be referred to as a cool dial), etc. The first general processing unit 201 is further configured to control the first graphics processing unit 202. For example, when the first general processing unit 201 detects that the electronic device is in a 3D dial application scene, the first graphics processing unit 202 is controlled to perform processing of 3D graphics. The first general processing unit 201 is further configured to send communication information to the second general processing unit 203, or receive communication information sent by the second general processing unit 203, for example, the communication information may be a handover instruction.

The first graphics processing unit 202 may be used to process complex graphics displayed by a display screen. For example, when the electronic device is in a 3D dial application scenario, the first graphics processing unit 202 enters a working state, performs processing of 3D graphics, and controls a display unit in the electronic device to display the 3D graphics.

The second general processing unit 203 may be configured to detect power consumption of the electronic device or an application scenario, where the application scenario may include, for example, a 2D dial, a time display, a sports health, an information display, a mobile payment, a mobile phone call, a video playing, a music playing, or a 3D dial. The second general processing unit 203 is further configured to control the second graphics processing unit 204. For example, when the second general purpose processing unit 203 detects that the electronic device is in a 2D dial application scene, it controls the second graphics processing unit 204 to perform processing of 2D graphics. The second general processing unit 203 is further configured to send communication information to the first general processing unit 201, or receive communication information sent by the first general processing unit 201, for example, the communication information may be a handover instruction.

The second graphics processing unit 204 may be used to process simple graphics displayed on the display screen. For example, when the electronic device is in a 2D dial application scenario, the second graphics processing unit 204 enters a working state, performs 2D graphics processing, and controls a display unit in the electronic device to display the 2D graphics.

Since the first general processing unit 201 and the second general processing unit 203 are both available for detecting power consumption and application scenarios of the electronic device. The working process of the chip system is described below under different power consumption and different application scenes.

Alternatively, the first general processing unit 203 and the second general processing unit 203 may be powered on at the same time, or may be in a powered on state separately.

In a second possible embodiment, when the power consumption of the electronic device is greater than the preset threshold, the normal operation of the electronic device can be ensured only when the first general processing unit enters the power-on state. Specifically, the method may be determined according to actual requirements, which is not specifically limited in the embodiment of the present application.

At this time, the second general purpose processing unit 203 may detect an application scenario of the electronic device, and when the electronic device is in any one application scenario of display of a complex graph, audio display, or communication scenario, for example, display of a 3D graph (may also be referred to as display of a 3D dial), mobile payment, mobile phone call (cellular phone call), video playing, or audio playing, the operation process of the chip system is similar to the operation process when the power consumption of the electronic device is greater than the preset threshold, and the specific operation process may refer to the above description and will not be repeated herein.

Further, as shown in fig. 4, the chip system further includes: at least one cooperating unit 206. Both the first general purpose processing unit 201 and the second general purpose processing unit may control the operation mode of the at least one co-ordinating unit 206. Illustratively, during the process of controlling the electronic device by the second general purpose processing unit 203, the at least one coordination unit 206 may be controlled to enter a low frequency low voltage mode; during the control of the electronic device by the first general processing unit 201, the at least one co-unit 206 may be controlled to enter a high frequency high voltage mode.

Wherein the at least one coordination unit 206 may include at least one of: a communication unit 01, a display unit 02, and a power supply unit 03. The at least one coordination unit 206 is illustrated in fig. 4 as including a communication unit 01, a display unit 02, and a power supply unit 03.

The power supply unit 03 may be used to power the first general purpose processing unit 201 and/or the second general purpose processing unit 203.

For ease of understanding, the chip system shown in fig. 5 is exemplified. The chip system includes: a high performance processor core, a 3D graphics rendering core, a low power processor core, a 2D graphics rendering core, a power supply unit, a memory control system, a memory device granule, a display control system, and a display screen. The functions and the working processes of each unit are similar to those of each unit in the chip system shown in fig. 4, and refer to the related description in fig. 4 specifically, and are not repeated here.

In a possible embodiment, the first general purpose processing unit 201 shares the at least one co-unit 206 with the second general purpose processing unit 203. For example, the electronic device may access the storage unit 205 through the first general processing unit 201 and control the display unit 02 to display information stored in the storage unit 205. Or the electronic device may access the storage unit 205 through the second general processing unit 203 and control the display unit 02 to display information in the storage unit 205. In this embodiment, the electronic device shares the communication unit 01, the display unit 02 and the power unit 03, so that the first general processing unit 201 and the second general processing unit 203 ensure that the electronic device can work normally in the process of switching between them, that is, the display screen of the electronic device is not turned off (i.e. seamless switching is implemented) in the switching process.

Optionally, when the electronic device is started, the second general processing unit is further configured to enter a power-on state, and control the second graphics processing unit to enter the power-on state; wherein the first general processing unit does not enter a power-on state. In this embodiment, when the electronic device is started, the second general processing unit enters the power-on state, the first general processing unit does not enter the power-on state, and the power consumption of the first general processing unit is greater than the power consumption of the second general processing unit, so that the power consumption of the electronic device is reduced.

Further, when the electronic device is in the sleep state, the power consumption of the electronic device is less than or equal to the preset threshold. At this time, the working process of the chip system is the same as the working process when the power consumption of the electronic device is less than or equal to the preset threshold, and will not be described herein.

The RICH OS comprises a CPU and a 3D GPU, and is used for supporting the electronic equipment to enter application scenes such as a 3D dial, a cellular call and video playing, and the RTOS comprises an MCU and a 2D GPU, and is used for supporting the electronic equipment to enter application scenes such as a 2D dial, a Bluetooth call and sports health. Because the RICH OS and the RTOS are integrated on a chip and share the at least one cooperative unit, the electronic equipment can work normally in the process of switching the RICH OS and the RTOS, namely, the display screen of the electronic equipment is not turned off in the switching process (namely, seamless switching is realized). It should be noted that the functions of each unit in the chip are similar to those of each unit in fig. 4, and will not be repeated here.

Optionally, the at least one synergistic unit may be integrated with the first general purpose processing unit 201 (CPU), the first graphics processing unit 202 (3D GPU), the second general purpose processing unit 203 (MCU), the second graphics processing unit 204 (2D GPU), and the storage unit 205 on a chip, or may not be integrated on a chip, which is not specifically limited in the embodiments of the present application.

In practical applications, the electronic device may be a wearable device, for example, the electronic device may be a smart watch or the like.

In the embodiment of the application, when the power consumption of the electronic device is smaller than or equal to the preset threshold (i.e. when the electronic device is in a low power consumption state), the second general processing unit enters a power-on state, the electronic device can be controlled directly through the second general processing unit (i.e. the low power consumption processing unit), the second general processing unit does not need to wait for the electronic device to be in a dormant state (i.e. a screen-off state), the second general processing unit controls the electronic device, and the second graphics processing unit enters the power-on state, neither the first general processing unit nor the first graphics processing unit enters the power-on state, the power consumption of the first graphics processing unit is larger than the power consumption of the second graphics processing unit, and the power consumption of the first general processing unit is larger than the power consumption of the second general processing unit, thereby reducing the power consumption of the electronic device. On the other hand, the chip system is realized by adopting a single chip, so that the cost of the electronic equipment is further reduced.

Fig. 7 is a schematic flow chart of a control method according to an embodiment of the present application, where the control method is applied to the chip system shown in fig. 4, and the control method includes the following steps.

S701: when the power consumption of the electronic device is greater than a preset threshold, the first general processing unit 201 and the first graphics processing unit 202 enter a power-on state.

Alternatively, the first general purpose processing unit 201 may also be referred to as a high power consumption processing unit, for example, the first general purpose processing unit 201 may be a high performance processor core. In one example, the first general purpose processing unit 201 is a central processing unit (central processing unit, CPU).

Optionally, the first graphics processing unit 202 is configured to process complex and high-precision graphics, for example, the first graphics processing unit 202 may be a three-dimensional (three dimensional, 3D) graphics processing unit, and may be configured to process 3D graphics, for example, when the electronic device is in a 3D dial application scenario, the first graphics processing unit 202 enters a working state to process 3D graphics. The first graphics processing unit 202 may be a 3D graphics rendering core. In one example, the first graphics processing unit 202 is a three-dimensional graphics processor (three dimensional graphics processing unit,3D GPU).

Second, the first general processing unit 201 and the first graphics processing unit 202 may also be referred to as a high power consumption processing system. The high power processing system may also be referred to as a high performance processing system or a multifunctional operating system (RICH operating system, RICH OS), which may support the electronic device to enter complex (RICH) application scenarios, for example, the high power processing system may support the electronic device to enter application scenarios such as 3D dial, video playing, mobile phone (including cellular phone), and music playing.

It should be noted that, the first general processing unit 201 entering the power-on state includes the first general processing unit 201 entering the power-on state and entering the working state. The first gpu 202 entering the power-up state includes only the first gpu 202 entering the power-up state and not entering the operating state. When the electronic device needs to process graphics, the first general processing unit 201 controls the first graphics processing unit 202 to enter a working state.

Further, the first general processing unit 201 detects the power consumption of the electronic device, and when the power consumption of the electronic device is greater than a preset threshold, the first general processing unit 201 controls the first graphics processing unit 202 to enter a power-on state and controls a display screen in the electronic device. The first general processing unit 201 may send communication information to the second general processing unit 203 or receive communication information sent by the second general processing unit 203, for example, the communication information may be a handover instruction.

S702: when the power consumption of the electronic device is less than or equal to the preset threshold, the second general processing unit 203 and the second graphics processing unit 204 enter a power-on state, and the first general processing unit 201 and the first graphics processing unit 202 enter a power-off state.

Alternatively, the second general-purpose processing unit 203 may also be referred to as a low-power processing unit, for example, the second general-purpose processing unit 203 may be a low-power processor core. In one example, the second general purpose processing unit 203 is a micro control unit (micro controller unit, MCU). The power of the first general purpose processing unit 201 is greater than the power of the second general purpose processing unit 203.

Wherein the power of the first graphics processing unit 202 is greater than the power of the second graphics processing unit 204, the second graphics processing unit 204 is configured to process simple graphics. For example, the second graphics processing unit 204 may be a two-dimensional (2D) graphics processing unit, and may be configured to process 2D graphics, for example, when the electronic device is in a 2D dial application scenario, the second graphics processing unit 204 enters a working state and performs processing of 2D graphics. The second graphics processing unit 204 may also be a 2D graphics rendering core. In one example, the second graphics processing unit 204 is a two-dimensional graphics processor (two dimensional graphics processing unit,2D GPU).

The second general processing unit 203 and the second graphics processing unit 204 may be referred to as a low power processing system. The low power processing system may also be referred to as a real-time operating system (RTOS), and may support the electronic device to enter into a simple application scenario, such as any one of a 2D dial, bluetooth talk, time display, sports health, and information display.

It should be noted that, the second general processing unit 203 entering the power-on state includes the second general processing unit 203 entering the power-on state and entering the working state. The second gpu 204 is only powered on and the second gpu 204 is powered on, but not in an operating state, and the second cpu 203 controls the second gpu 204 to be in an operating state when the electronic device needs to process graphics.

In addition, the first general processing unit 201 and the second general processing unit 203 are two processing units that are independent from each other, that is, the first general processing unit 201 and the second general processing unit 203 can be independently powered on.

Alternatively, the first general processing unit 203 and the second general processing unit 203 may be powered on at the same time, or may be in a powered on state separately. For example, in a first possible embodiment, when the power consumption of the electronic device is greater than the preset threshold, the first general processing unit and the second general processing unit both enter a power-on state. In a second possible embodiment, when the power consumption of the electronic device is greater than the preset threshold, the first general processing unit enters a power-up state, and the second general processing unit enters a power-down state. Specifically, the method may be determined according to actual requirements, which is not specifically limited in the embodiment of the present application. In the following embodiments, the first general processing unit 203 and the second general processing unit 203 are separately in the power-on state will be described as an example.

Further, the system on chip further includes a storage unit 205, where the storage unit 205 may be configured to store information in the electronic device, for example, the information may include payment information, time information, and the like, and the storage unit 205 may include a memory (for example, the memory may be a random access memory), where one of the first general processing unit 201 and the second general processing unit 203 accesses the memory at the same time. For example, when the first general purpose processing unit 203 and the second general purpose processing unit 203 are separately in a power-on state, the general purpose processing unit in the power-on state accesses the memory. The first general purpose processing unit 203 accesses the memory while the first general purpose processing unit 203 and the second general purpose processing unit 203 are simultaneously in a powered-on state.

In the first case, the operation of the chip system under different power consumption will be described.

At this time, the first general processing unit 201 may detect an application scenario of the electronic device, and when the electronic device is in any application scenario such as a 2D dial, time display, motion health, or information display, the working processes of the first general processing unit 201 and the second general processing unit 203 are similar to the working process when the power consumption of the electronic device is less than or equal to the preset threshold, and the specific working process may refer to the above description and will not be repeated herein.

In another possible implementation, the second general processing unit 203 and the second graphics processing unit 204 are in a power-on state, the second general processing unit 203 accesses the storage unit 205 and controls the display of the display screen in the electronic device, and the second graphics processing unit 204 is configured to process the graphics displayed on the display screen. At this time, the second general processing unit 203 may detect an application scenario of the electronic device, and when the electronic device is in any application scenario such as mobile payment, mobile phone call, video playing, music playing, or 3D dial, the operation of the first general processing unit 201 and the second general processing unit 203 is similar to the operation state when the power consumption of the electronic device is greater than the preset threshold, and the specific operation process may refer to the above description and will not be repeated here.

Further, the system-on-chip further comprises at least one co-unit 206. Both the first general purpose processing unit 201 and the second general purpose processing unit 203 may control the operation mode of the at least one co-ordinating unit 206. Illustratively, during the process of controlling the electronic device by the second general purpose processing unit 203, the at least one coordination unit 206 may be controlled to enter a low frequency low voltage mode; during the control of the electronic device by the first general processing unit 201, the at least one co-unit 206 may be controlled to enter a high frequency high voltage mode.

Wherein the at least one coordination unit 206 may include at least one of: a communication unit 01, a display unit 02, and a power supply unit 03.

The functions of the respective units included in the at least one cooperative unit 206 will be described below.

Wherein the communication unit 01 can be used to support the chip system for communication.

In a possible embodiment, the first general purpose processing unit 201 shares the at least one co-unit 206 with the second general purpose processing unit 203. For example, the electronic device may access the storage unit 205 through the first general processing unit 201 and control the display unit 02 to display information stored in the storage unit 205. Or the electronic device may access the storage unit 205 through the second general processing unit 203 and control the display unit 02 to display information in the storage unit 205. In this embodiment, the first general processing unit 201 and the second general processing unit 203 share at least one coordination unit 206, so that the first general processing unit 201 and the second general processing unit 203 ensure that the electronic device can work normally in the process of switching between them, that is, the display screen of the electronic device is not turned off (i.e. smooth seamless switching is achieved) in the process of switching.
